In a medium bowl or the bowl of a stand mixer fitted with the paddle attachment, place ½ cup of unsalted butter at room temperature and 1 cup of granulated sugar. Beat on medium speed until light and fluffy (about 1-2 minutes).
In a separate medium bowl, whisk together the 2 cups of all purpose flour, ½ cup of almond flour, 1 tsp of baking powder and ¼ tsp of salt until combined.
Scrape down the sides of the bowl of butter and sugar mixture and then add 1 egg, 1 tsp of vanilla extract and ¼ tsp of almond extract. Mix until combined.
Add the dry ingredients to the wet ingredients and mix until combined. Do not overmix.
Turn the dough out onto a lightly floured surface and bring it together by hand until it looks like a homogenous dough.
Place the dough onto the parchment paper you will use to bake the cookies and roll out to ¼ inch thickness.
Use your desired cookie cutter to cut out the cookie shapes. I used a 3" cutter for the cookies and a 1" cutter for the center. You will cut out two cookies per sandwich cookie. Half of the cookies leave as is, the other half cut out a small shape in the middle for the jam to peek through. Remove the excess dough from around the shapes.
Combine the excess dough on a lightly floured surface and roll out again to ¼ inch thickness. Cut out the remaining shapes and place on the parchment paper.
Once all cookies have been cut out and place on the parchment paper, including the 1" centers that you cut out if you want an extra cookie snack. Place the parchment paper onto the baking sheet that you will use to bake later on.
Refrigerate the cookies for just 30 minutes. Cookies should feel firm to the touch before placing in the oven.
Towards the end of the 30 minutes of chill time, preheat the oven to 350℉ (roughly 180℃)
Remove the cookies from the refrigerator and bake for 10 minutes.** Allow the cookies to cool completely.
